I am the main author of 2 papers evaluating the Topics API from Google: [1] and [2] and working on more research in that space.
I have also started compiling different papers and analyses on projects like the Privacy Sandbox initiative from Google (https://privacysandstorm.com/proposals/) as well as releasing other resources (datasets, tools, etc.), contributions welcome if you are interested!
Best,

at the end of the day it seems like 90% of people using google products dont even care. while some even prefer the convivence of some features that directly save your info. not sure what percentage that is compared to the people that practice a lot privacy.
but shown by the chrome market share google really doesnt have to care about this section of users. the fact theyre willing to try things is a good sign imo. either way in 2024 to be complianing about google is funny to me. literally dont have to interact or use a google product, they already have your information and so does the internet better to not let them occupy any of your mind as well
